Chemical Reactions at Solid/Solution Interfaces and in Aerosols

本研究项目由分析和表面化学项目支持，主要研究胶体分散体的制备、性质和相互作用。合成和物理表征的结合用于了解这种精细划分状态下物质的性质，特别是这些材料的光学，磁性，电学和吸附性质。采用双射流和三射流沉淀法合成了纳米级颗粒。这些材料的物理特性将集中在粘附现象上。非常精细分割的固体的磁性和光学性质在磁性记录装置、填料和涂层中有许多实际应用。了解这些材料的合成，以及它们的性质与颗粒大小和形态的控制之间的关系是本研究项目的重点。化学合成和物理表征相结合，发展这些有趣的和技术上重要的材料的理解。

This research project, supported by the Analytical and Surface Chemistry Program, is concerned with the preparation, properties, and interactions of colloidal dispersions. A combination of synthesis and physical characterization is used to understand the properties of matter in this finely divided state, particularly the optical, magnetic, electric, and adsorptive properties of these materials. Nanoscale particles are synthesized using double and triple jet precipitation methods. The physical characterization of these materials will focus on the adhesion phenomena. The magnetic and optical properties of very finely divided solids have many practical applications in magnetic recording devices, fillers, and coatings. An understanding of the synthesis of these materials, and a correlation of their properties with the controlled size and morphology of the particles is the focus of this research project. Chemical synthesis and physical characterization combine to develop an understanding of these interesting and technologically important materials.
